cant get NXT to connect to controller station via bluetooth

[cougarbotics]

we are using the program NXT-G. we can get the NXT to connect to the controller station by USB, but we cannot get it to connect by bluetooth. we think that maybe our bluetooth adapter (the thing that looks like a jump drive) is corrupted. we have tried using different computers, but cant it to work on either. any suggestions on what to do? is it that our NXT isnt connecting? please help. our competition is only days away.

If you think your adapter is corrupted, then you would have to call Pitsco and ask for a replacement immediately.

Are you using the proper firmware?

You might want to call Pitsco anyways to find out what's going on.

Make sure you have your blue tooth drivers installed and working.

Also do you have to pair the computer to the NXT?

Just for the record, I moved this thread into the FTC forum.

Have you added the NXT brick to your computer as a bluetooth device?

- Verify that the Bluetooth Dongle is using the Generic Windows Driver.

- Is the NXT battery fully charged?

- Is the NXT Bluetooth turned on and not set to invisible?

- Is the NXT buried behind too much metal, preventing the signal from reaching the controller?

- Is the NXT too close to an active 802.11 a,b,g or N WiFi system? Turn off the WiFi source or move further away.

- Is the correct NXT name entered into the Robot Control Station?

- Are you able make a Bluetooth connection to the NXT using NXT-G? If yes, close the NXT-G program before starting the Robot Control Station.

- Remove the NXT battery for 15 seconds and try to make a Bluetooth connection.

- Run the Windows Bluetooth Device Manager. Does the NXT appear in the list of devices? Delete the NXT and re-establish a Bluetooth connection using the Bluetooth Device Manager. Next, try to connect to the NXT using the Robot Controller Station.

- Run the Windows Bluetooth Device Manager.
----Select the NXT from the device list
----Select the Properties Button
----Select the Services tab at the top of the Properties window
----The Properties Window will switch to an empty Services window with an animated flashlight to depict searching for available services for the device chosen
----When the animated flashlight finishes searching, a service (Serial port (SPP) 'Dev B') should be listed. Verify that the check box to the left of the service is checked.
----Select OK at the bottom of the Services Window
----Using the Robot Controller Station, try to establish a Bluetooth connection (up to 4 tries)

- Is the latest FTC NXT-G firmware installed on the NXT?

- Have you tried a different computer? Some brands of notebooks can insist on using a manufacturer's driver instead of the Generic Windows Driver. The Generic Windows Driver should be used.

- Did the Passkey screen appear on the NXT display? If yes, did you press the Orange button on the NXT to approve the Passkey?

- Is the NXT using the default Bluetooth Passkey (1234)?
